OK so I know which bumpers and skid plates I want to get. I am trying to get a weight average on those to determine spring rates for the suspension I wanna buy. I am looking for opinions on the OME ultimate and Super ultimate setups. What I am wanting to know is with either of these setups, do i still need the SYE and new drive shaft or are these complete kits. I am impressed with the hardware these kits come with, I just wanna make sure it's all i need to buy before i get started. I don't wanna have the jeep tore down and realize i need another part thats a week away. I intend to run 33-12.50-15's on 15x8's with 3-3.50 backspace if that helps anybody with my questions. Thanks for the help everyone.
